•Class 3 Public Primary Certification Authority
•Deutsche Telekom
•DigiCert Global Root CA
•Entrust
•Global Sign
•GoDaddy

Minimize certificate cost Scenario
Balance the cost and security Scenario
Maximize security
Description This scenario is for companies that want to
pair many SBCs or change them frequently This scenario is good for companies that do not
change the gateways frequently.
In the example below. a company has four SBCs
(gw1.contoso.com; gw2.contoso.com;
gw3.contoso.com; gw4.contoso.com). In this scenario the company assigns a
certificate to each gateway. There is only
one certificate for every gateway.

Subject name gw.contoso.com gw1.contoso.com gw1.contoso.com
SAN *.contoso.com  gw1.contoso.com
 gw2.contoso.com
 gw3.contoso.com
 gw4.contoso.com
 gw1.contoso.com gw1.contoso.com

Phase Admin Steps
One-time global config •Configure SfB hybrid, if not already done
•Pair the SBC and Teams PSTN edge
•Create online voice routing policy/Export voice routes from onprem voice policy
•Create online dial plans/Export dial plans from on premises
Configure TeamsUpgradePolicy

•Set tenant -wide policy to mode= SfBwithTeamsCollab
Assign licenses and set policy •Adjust Teams Policies as required for org
•In O365, assign Teams license, if not already assigned
Notification phase Optional : In on -prem, grant TeamsUpgradePolicy (w/ NotifySfBUsers =true) to pilot users
Upgrade •In on -prem: run Move -CsUser with MoveToTeams switch
•On SBC: Configure voice routing to enable incoming calls (start sending calls to Direct Routing instead of
routing them to Mediation Server)
•In O365 (after 4 hours): Enable Outgoing calls: Assign voice routing policy to migrated users and
optionally any dial -plans

•Creating user objects on Azure AD
•All routing is done by the center SBC

Analog device in Teams – Roadmap
•Calls can go all the way up to Teams ( for CDRs) , Teams will loop
back
•Analog line Presence reporting to Teams – no ETA
•MWI – No ETA

•Central SBC
•No breakout at the branches
•User is internal
•User located in a remote branch •Central SBC
•No breakout at the branches
•User is External
•Media will go to the Central SBC
external interface •Central SBC
•Each Branch has a local GW/SBC
•User is Internal
•User located in his “Home” branch
•Call be routed to the local
breakout
•Media will stay local •Central SBC
•Each Branch has a local GW/SBC
•User is Internal
•User located not in his “Home”
branch
•Call be routed to the user home
breakout
•Media will go between branches,
directly to the GW/SBC •Central SBC
•Each Branch has a local GW/SBC
•User is Internal
•User located not in his “Home”
branch
•Call be routed to the user home
breakout
•Media will go via the central SBC (
the connection between sites is
not good) Media Optimization – solution

•AudioCodes SBC will support new SIP header by Teams SIP HUB.
•The new headers will include information about the user location
•External or Internal to the corporate network
•The user real time Site location identification ( of the device/client
which is making the call )
•The SBC will then preform smart call routings and media path
handling ( in complex topology ARM can simply)
•TAP by the end of Sep
•Note – the user location will be identify by Teams with the LIS
online function

Mediant Optimization enhancement
•Allow the IT easy and simplify way to build the online line “LIS” –
adding a new section to the UMP ( it is the same LIS for LBR and
E911)
•SBC Enhancement – the routing decisions will be made by the
central SBC , the SBC will include an additional tables for Routing
and media handling (site 2sites etc) – 7.4

Direct Routing SBC support new capabilities
•Audio Conferencing with Direct Routing for GCC High and DoD
•https://docs.microsoft.com/en -us/microsoftteams/audio -conferencing –
with-direct -routing -for-gcch -and-dod
•Call Queue and AA supports ( with resources accounts )
•Teams calling API for inbound calls via DR SBC

Teams site Resiliency
•Two options
•SD-WAN for full site resilience ( Shaul session )
•Teams site resiliency for Teams clients and Teams native phone
•“SBA like “ products
•MS will provide a HTTP proxy code, AudioCodes will run the code on an OSN .
•AC will develop a full zero touch and configuration layer
•The local SBC shell have two DR pair with Teams and with the local proxy
•The Proxy will get the site dial plan and configuration from the cloud
•The Teams clients and the IPP , will fail over to the proxy , trigger by a WAN fail
•ETA – Q1Y2020
